Just got ASUS ET12 mesh routers set up and having issues when 6GHz is enabled. When it is on my outside ring cameras have serious issues connecting to the 2.4GHz Wi-Fi. Some won’t connect at all. It’s almost like the range of the 2.4GHz is severely lessened when 6GHz is on. As soon as I turn off 6GHz they all connect and work fine. I have smart connect turned on for 2.4 and 5. I have tried having fully separated too though and same issue. I have 3 units using wired back haul at various points in my house. So coverage should be really good, even outside, and is as long as I keep 6GHz off. Which is not ideal as that’s why I bought these routers.
